Smart serial with Mesa 6i24 + 7i47 + 7i73 was created by Raimundus
Hello Linuxcnc forum,
I am trying to set up a smart serial connection between a Mesa 6i24 board (which runs in 5i24 compatibility mode) and a 7i73. In between these, I use a 7i47 interface board. My problem is that the smart serial device is not detected by linuxcnc.
When loading the hm2_pci module, the red CR1 LED on the 7i73 is always red (indicating a watchdog error) and the green CR2 led flash on for a short moment but then stays off.
I load the system with:
Attached is the output log. The important lines areindicating that no smart serial device was found.
Do you have any ideas what the problem could be?
Below is a detailed guide of our setup:
This is how I installed the system:
Step 1: Hardware
Step 2: Firmware flashing
It seems that the 6i24 requires a mesaflash. We flashed it with
Step 3: Load the software:
Attached is the log

You don't need the "firmware=" part of the loadrt hm2_pci line for cards like the 6i24 where the firmware is flashed in. However that isn't the problem as the firmware= will just be ignored.
I think that the problem is that your bitfile is intended for the 7i44. It has a full 50-pin connector of smart-serial.
I think you need a firmware such as 5i24_25_sv4_7i47s.bit which mixes encoders, pwm and smart-serial on the same connector to suit the 7i47.

Hi Andy . Thank you so much for your insight. This is very helpful indeed.
Before I try the new bit file I have 2 further questions: how do you know that the bit file that I'm using is intended for the 7i44? Is this documented somewhere?
Furthermore isn't the 5i24_25_sv4_7i47s.bit file for 25bit version of the 5i24, and since I have the 16bit I should probably use the 5i24_16_sv4_7i47s.bit right?
Sorry if these are very basic questions, this is all new to me.

I know that the 7i44 is one complete 50-pin header for 8 channels of smart-serial.
Yes, that is correct, Use that one.

Only indirectly. I was comparing the pin layout in the bitfile source vhdl files to the pin layouts of the various daughter-boards.how do you know that the bit file that I'm using is intended for the 7i44? Is this documented somewhere?
